Bedfordshire town in which fictional aviator has to paddle (11)

I believe the answer is:

biggleswade

I'm a little stuck... Click here to teach me more about this clue!

'bedfordshire town' is the definition.
(I've seen this before)

'fictional aviator has to paddle' is the wordplay.
'fictional aviator has' becomes 'biggles' (I can't justify this - if you can you should give a lot more credence to this answer).
'to paddle' becomes 'wade' (I've seen this before).
'biggles'+'wade'='BIGGLESWADE'

'in which' acts as a link.

Can you help me to learn more?

(Another definition for biggleswade that I've seen is " Bedfordshire town".)
